中东地区滩相储层岩石分类方法研究进展

摘 要：中东地区普遍发育滩相孔隙型灰岩储层，孔隙类型多，孔喉结构复杂，常规的储层分类难以满足储层精细刻画的需求。笔者总结了近年来针对中东地区滩相孔隙型储层的岩石结构分类、孔隙分类、物性分类、核磁共振分类及测井资料分类五种分类方法，这些分类方法可用于类似孔隙型碳酸盐岩油气藏的开发。

Abstract：Because beach facies porous limestone reservoirs are widely developed in the Middle East， with many pore types and complex pore throat structure， the conventional reservoir classification is difficult to meet the needs of fine reservoir characterization. The author summarizes the five classification methods of rock structure classification， pore classification， physical property classification， nuclear magnetic resonance classification and logging data classification for beach facies porous reservoirs in the Middle East in recent years， which can be used for the development of similar porous carbonate reservoirs.

Keywords：carbonate rock;rock classification;pore throat structure
